Here are the engine block # results from Mortec.
The wrecked engine; 10066036...350...........2 or 4...Target Master/Goodwrench crate motor, 2-piece rear
seal, "Hecho en Mexico"
And the used replacement I got. Guess its not necessarily 72 as I was told, but in the range. Says its a replacement block.
3970014....350...70-76...2 or 4
Sorry, its a flex plate, not a flywheel (showing my inexperience here), that mates to a 700R transmission. I just compared the two and they are the same size and thickness and both in good shape (teeth etc). So I guess to be sure its all balanced correctly, I'll use the same flex plate and balancer (the larger one) that came on the replacement engine. I do also have the timing pointer for the larger balancer that I will use (other one wouldn't fit anyway).
I've cleaned it up, given it a little paint touch up, and am replacing all the seals (except head gaskets of course), installing a high volume oil pump, new thermostat, oil pressure and temp sensor.
I switched the timing chain cover over as the other one was nicer chrome. It had a newer seal in it so I left it (@78buckshot, is this the crankshaft seal you mention replacing? I did use a new gasket and also black gasket maker per many youtube vids for a good seal. Sound ok?
